In March of 2000, the United States Secretary of Agriculture declared an extraordinary emergency in order to prevent the spread of the virus from Pennsylvania to the rest of the United States and to other countries. The emergency declaration allowed the United States Department of Agriculture (USDA) to provide the funding necessary for eradication and to pay compensation to affected growers. Through surveying and removal of infected and exposed trees, PPV was eradicated from Pennsylvania. The Federal plum pox quarantine for Pennsylvania was rescinded on October 29, 2009, following 3 years of negative survey results.
In 2006, PPV was detected in Michigan. A single plum tree located at a Michigan State University facility located near Benton Harbor, Michigan was determined to be infected with PPV. The infected tree was destroyed and, through trace-forward and trace-back investigations, no additional trees in Michigan were found to be infected with PPV. The Michigan Department of Agriculture rescinded their PPV quarantine on September 2, 2009.
PPV was detected in New York State in 2006 and was declared eradicated in 2019. While federal interstate movement restrictions will no longer be in effect for portions of Orange and Ulster Counties, certain New York state regulations will remain in place for portions of these counties. Specifically, New York state regulations still prohibit PPV-host plant propagation, including budwood collection and nursery plantings in state regulated areas. However, people may once again plant PPV-host Prunus trees for fruit or ornamental purposes in what was once a “no plant zone.”
On October 17, 2019, USDA declared the eradication of PPV from the United States. From the beginning, the plum pox virus eradication program was a cooperative effort among USDA’s Animal and Plant Health Inspection Service and Agricultural Research Service, departments of agriculture in impacted states, the Tuscarora Nation, industry, academia, growers, and homeowners.
